SAND AND GRAVEL 



The production of sand and gravel should be given consideration 

 as one of the branches of the mineral industry. It is carried on in 

 one or more places in practically every county of the State; but 

 only in a few sections has it become really stabilized so as to be 

 conducted on a more or less permanent basis. For that reason a 

 statistical investigation of the industry is attended with considerable 

 difficulty, and the results may be lacking somewhat in accuracy. 



Such is the case more especially with the ordinary building sands 

 and gravels which are so widely distributed that in most places 

 they have little or no intrinsic value, the requirements being sup- 

 plied from deposits in the immediate vicinity at a nominal expense 

 above the cost of handling. In recent years, however, there has 

 been a manifest tendency toward a standardization of these 

 materials when they are to be employed in important structures or 

 engineering works. It has been found that they have a very direct 

 influence upon the quality of the mortar or concrete into which 

 they enter, a fact that has not received so wide appreciation as it
